E-line Rigid 8"x2" Polyurethane (TPU) USA-Made Wheel 4"x4.5" Plate Caster w/ Tread Lock Brake; Part# ER8X2TUMBTBK

About This Caster - ER8X2TUMBTBK

Set this 8-inch E-line rigid on the braked back corner of the biggest tow cart that parks on a dock, the TPU polyurethane caster whose firm maroon tread carries the load while a precision ball bearing rolls the tallest rear cool and a tread lock holds it against roll-back.

A rubber wheel flattens under load and a plain bore heats on a long pull; the Pemco TUM polyurethane tread on a polypropylene core holds its shape under the E-line load and stays non-marking, the precision ball bearing runs cool and true, and the tread lock clamps the rear so a big cart on a dock slope cannot roll back. The 8-inch diameter rolls over expansion joints and dock plates, and the 4 by 4-1/2 top plate bolts to a flat deck. USA-made for fast shipping.

Ideal applications

• Braked back corners of the biggest tow carts on a dock
• Cool precision roll under a braked tallest rear
• Biggest towed loads that flatten a rubber wheel

Skip the polyurethane wheel if the cart works near heat over 180°F or on oily floors; a phenolic E-line wheel withstands oil and heat to 250°F where TUM gives.

Pairs with: the ER8X2TUMTBK roller tread lock on a mixed-bearing rig.
